N Collins,
Catalyst:
GCSE Science Review,
2004, Vol 15, Issue 1,
pages 8-10.
|
| Summary:
Oxygen is essential for most respiration, which goes on in all live cells, all living things, all the time. Look at how organisms get the oxygen they need from their surroundings and how it reaches cells. Also explore how we monitor oxygen transport, which is vitally important in medical care. |

pages 11-12.
|
| Summary:
Go for a walk on a crisp winter’s morning and the chances are that the only animals you’ll see will be mammals or birds — certainly no lizards or frogs. How is it that birds and mammals are up and about, whatever the weather? This article looks at why homeostasis matters. |

|
| Summary:
You may have wondered why the real-life food chains you have studied aren’t very long. In this article we show how the loss of energy from food chains limits the number of animals that can survive on the energy fixed by a patch of vegetation. |
